Regatta is a distributed ETCD inspired key-value store. Regatta is designed to operate eiter as a standalone node, standalone cluster or in Leader - Follower mode suited for distributing data in distant locations. e.g. in different cloud regions. While Regatta maintains many of ETCD features there are some notable differences:
- Regatta is designed to store much larger (tens of GB) datasets and also provide iterator-like API to query large datasets.
- Regatta prioritize speed and performance over some more advanced ETCD features like Watch API, or Leases.
- Regatta support multiple separate keyspaces called tables which operate individually.
- Even though Regatta has not yet reached the 1.0 milestone it is ready for a production use.
- There might be backward incompatible changes introduced until version 1.0, those will always be flagged in the release notes.
- Builds for tagged versions are provided in form of binaries in GH release, and Docker images.
- Tagged releases are suggested for production use, mainline builds should be used only for testing purposes.
- You need to distribute data from a single cluster to multiple follower clusters in edge locations.
- You need a local, persistent, cache within a data center and reads heavily outnumber writes.
- You need a pseudo-document store.
